Embodiment 1

[0042] Embodiment 1: On-line measurement for on-line production of self-cleaning glass:

[0043] The following is the test result of the same batch of production samples measured by the present invention and other existing methods:

[0044] Three groups of 100mm×100mm samples were taken from the same original float glass sheet in the production line, and the number of each group was the same, for comparative experiments.

[0045] 1) the first group, adopt the method test of the present invention;

[0046] The relative humidity in the test room is 50%±5%, the humidity variation range is ±2%, and the temperature is 23±1°C. The test method adopts the pendant drop method, and the calculation method adopts the θ / 2 method. This group uses the SL series contact angle tester to measure. The analysis system of the SL series contact angle tester is the CAST software system. The software system is installed in the computer, and then the contact angle tester is connected to the computer...

Embodiment 2

[0069] Embodiment 2: The method of the present invention is used to test the contact angle of super-hydrophilic self-cleaning glass.

[0070] The contact angle of super-hydrophilic self-cleaning glass is very small, also called hydrophilic angle, generally less than or equal to 3°. When the contact angle measured by the general contact angle tester is less than or equal to 3°, it is difficult to use the general test method. Accurate measurement; and the measuring result of the measuring method of the present invention is also more accurate to this situation, and error is below 1 °. The following is the application of the present invention in testing the hydrophilic angle of superhydrophilic self-cleaning glass:

[0071] In the test of the hydrophilic angle of the superhydrophilic film layer, there is no need to make any adjustments in operation, and the measurement results are shown in Table 2, and Table 2 records the two measurement results.

Abstract

The invention provides an on-line measurement method for the contact angle of self-cleaning glass, which adopts the actual use conditions closer to the self-cleaning glass film layer as the test condition, adopts the pendant drop method to test and the θ / 2 method to calculate, and can quickly and accurately measure on-line The contact angle of self-cleaning glass and related film layers, and can measure the contact angle of small angle more accurately.

Description

【Technical field】 [0001] The invention relates to a method for measuring the contact angle of self-cleaning glass, which is particularly suitable for on-line measurement of the contact angle of self-cleaning glass. 【Background technique】 [0002] The process by which a surface is wetted by a liquid and eventually spread is a very important aspect of surface chemistry. By the late 20th century, with the development of quantum electrodynamics and fine analysis processes, a large number of analysis methods were provided for surface chemistry, and the microscopic details presented between different interfaces and along the contact angle of the interface were discovered, and further understanding The mechanism of motion of liquids as they pass over surfaces, thus enabling detailed studies of contact angles during the study of wetting and spreading. [0003] When a liquid is dropped on a solid surface, depending on the nature of the system, the liquid will spread to cover the sol...
